what if I do and b then someone else c I don't have enough time pls
SETI program send <u>radio waves</u> for signs of transmissions from civilizations on other planets.
<u>Radio waves</u> have small frequency, how energy and high wave length
Answer:
d = 8.4 cm
Explanation:
In order to calculate the amplitude of oscillation of the top of the building, you use the following formula for the max acceleration of as simple harmonic motion:
(1)
A: amplitude of the oscillation
w: angular speed of the oscillation = 2f
f: frequency = 0.17Hz
The maximum acceleration of the top of the building is a 2.0% of the free-fall acceleration. Then, you have:
Then, you solve for A in the equation (1) and replace the values of the parameters:
The total distance, side to side, of the oscilation of the top of the building is twice the amplitude A. Then you obtain:
d = 2A = 2(4.2cm) = 8.4cm

Answer
given,
mass of two automobile = 1000 kg
speed of the two automobile = 20 m/s
let north be +y direction and east be +x directon.
a) from momentum conservation
m₁ v₁ + m₂ v₂ = (m₁ + m ₂) v
1000 × 20 - 1000 ×20 = (1000 + 1000)× v
v = 0 m/s [no direction]
b) from moment of momentum conservation in x-direction
1000 × 20 = (1000 + 1000)× v
_x
v_x = 10 m/s
from moment of momentum conservation in x-direction
1000 × 20 = (1000 + 1000)× v
_y
v_y = 10 m/s
Resultant =
= 14.14 m/s
